The Bigamist is an interesting film for its time and I enjoyed and appreciated that it didn't judge or make anyone out to be the bad guy at any point in the film. Instead the director holds a camera to the actions and lets the audience to decide for themselves. I don't recall ever having seen O'Brien in anything previously but feel he does some nice work here. I've never liked Fontaine better, and Lupino is equally solid as both actor and the films director. There were a few parts where the script was a little weak, but overall it was mostly solid. I did find the end slightly unsatisfying, but despite its shortcomings it's still worth a viewing.
